I Application tiled Aprl12, 1883. (No model.)

To alZZ whom it may concern..-

Be it known that 1,' JnrTHA BUNDY, of Barnesville, in the county ofBelmont and State of Ohio, have invented certain new and usefulImprovements in Attachments to a Force-Pump for Regulating the Stroke ofthe Piston; and I do hereby declare that the following is a full, clear,and .exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, which `formpart of this specification,

i in which-- l 1 Figure l is a side` elevation indicating, as a diagram,my improved link-motion.

Fig. 2 showsa mode o f transmitting motion to the links by hand fromthe. cab offa locomotive.

Figi?) is a cross-section through Fig. 1, taken 'in' the plane indicatedby dotted line' o: Fig. 4 is a cross-section through the same tigure,taken' vin the plane indicated by dotted line y y.

This invention relates to a new and improved link-motion, which isespecially designed for feeding water to the boiler, but which maydescribe the stroke of the pump can be regulated to work toits fullcapacity,4 or reduced to any desired quantity, and when it is necessarythe pump can be brought to rest. These movements are effected by mydevice without jar or concussions; By this invention I have completecontrol of the strokes of the pump, and consequently the boiler vcan besupplied with water at any time, regardless of the speed ofthe engine.

It will be seen that my link-motion can be attached to all engines,whether of the locomotive or stationary kind, where a pump is used forsupplying the boiler with Water.

In the annexed drawings, All designates a connecting-rod, which can beoperated by a wristpin on an eccentric, by a crank, or by a cross-headat B," and connected at Cl to the I lower. end of thelink D. This linkis connected 5 5 to the lifting-arm E by a pin or bolt in the center'ofthe cross-block F. The cross-block F is blocked out or set far enoughfrom the `link D to allow it to pass the slide-block G, as

this link is depressed by means of the lever II and lifting-arm E. l

When the link D is depressed until it rests on the slide-block G, thecenters or connecting-bolts are opposite and the pump pistonrod J ceasesto move while the engine is in motion. The slide-blockGiseonstructedwith lianges on one side, and by reason of its beingnconnected tothe pump piston-rod J by a bolt the link is confined to itsplace. The slideblock has a rocking motion upon the pivotal bolt whichconnects it with the pump pistonrod J, which allows it to accommodateitself to the motion of the link Das the link is raised and lowered.

y It is evident from what I have above described that the link-motioncan be operated from the cab vof a railroad-engine by using a longpitman-rod, as shown in Fig. 2, connected to the hand-lever H.

Having described my invention, what I claim as new, and desire `tosecure by Lett ers Patent, is-

1. The combination,witl1 a Apump-cylinder, of the piston-rod thereof,the slide G, the oscillating link to which said slide is applied,

the pitman A, the eccentric, the cross-block, the lifting-armE, thetoothed sector, and the lever latch arm, all constructed and adapted tooperate substantially in the manner and for the purposes described.

2. The combination of therectilinear reciprocating piston-rod, its angesiitted in the guides of the link D, the cross-head F, secured to thelink, the pitman-rod connected to the lower end of the link, thelifting-arm connected to the shaft of the hand-lever H, the toothedsegment, and a latching device applied to said hand-lever, allconstructed and adapted to operate substantially in the manner and forthe purposes described.

` In testimony that I claim the foregoing as my own I affix my signaturein vpresence of two witnesses.

JEPTHA BUNDY.
